If you're picking up an HTC First from HTC Corp. (TPE:2498) you have Facebook, Inc.'s (FB) new "Home" Android UI already preloaded. Otherwise, you may be able to install it today, as the app just went live.

The app is currently available (or will soon be available) for the:

Samsung Galaxy S4

Samsung Galaxy S3

Samsung Galaxy Note 2

HTC One

HTC One X/X+

Users with lower end Androids are out of luck for now, though Facebook CEO and founder Mark Zuckerberg promised to bring the OS down the food chain as the months roll by.

The reskin has drawn some controversy as Microsoft Corp.'s (MSFT) corporate communications director has accused the Zuck of scooping the "phones designed around people first" slogan for Facebook First from Microsoft's 2011 era "Put People First" Windows Phone campaign.

We understand why Facebook would want to find a way to bring similar functionality to a platform that is sadly lacking it. But as Android owners know, that platform is complicated enough without adding another skin built around another metaphor, on top of what is already a custom variant of the OS.

Ouch. But Android -- the world's most used smartphone platform -- has fans aplenty. The ultimate test will be what they make of the new release.

Early reviews aren't looking great -- the app has 2 and 1/2 out of 5 stars. Comment reviewers:

Your phone loses all functionality with this. I had to remove it instantly so I could use my phone. Facebook fails again.

Limits phone functionality, awkward interface, just weird and pointless. No widgets, doesn’t show date and time, can’t easily and quickly access basic functions such as phone (duh I need to make calls), texting, and camera. Uninstalled after 5 minutes.

Very poorly put together. Most homes support widgets and clocks and this one limits you severely. The only thing this does is puts FB on the screen all the time.

This is ridiculous. Maybe it's time for facebook to come out with their own facebook device? The one that can't do anything else but use facebook. It seems to be very close to what they accomplished here.
